In what has become a tournament of upsets, Dokic was one of three seeded players to lose Tuesday. The others were No. 4 Ai Sugiyama and No. 8 Tatiana Panova. Third-seeded Patty Schnyder was ousted Monday from the season's first clay-court event.

Dokic, a 19-year-old who didn't lose a set last year in the tournament, never got her game going. Suarez, ranked 29th in the world, won 6-3, 6-3.

The ninth-ranked Dokic is the only top-10 player in the $140,000 event.

"I am very disappointed, but that's the way it goes sometimes," Dokic said. "I hit too many errors and gave her too many free points."

The 22-year-old Suarez, who grew up on clay courts, said playing on her favorite surface was a significant advantage and helped negate Dokic's speed and power. The only time she didn't appear in control was in the second set, when she led 4-0 and Dokic came back with three straight games.

"All my life I play on clay and I feel a lot more comfortable on it," Suarez said. "I'm glad I played Jelena in the first round rather than after she played a couple of matches on this surface.

"On clay, the ball doesn't come at you so hard and I try to hit more softer shots. It's difficult for hard players."
